Verwenden
cAMP is used for intracellular signal transduction in many different organisms, conveying the cAMP-dependent pathway. Restoration of several morphological characteristics of normal fibroblasts in sarcoma cells when treated with adenosine-3': 5'-cyclic monophosphate. In the presence of adenosine 3':5'-cyclic monophosphate, protein kinase I dissociated into two subunits: a subunit binding adenosine 3':5'-cyclic monophosphate, and a catalytic subunit. Stimulation of calcium uptake in platelet membrane vesicles by adenosine 3',5'-cyclic monophosphate.
Application
The chief role of cyclic AMP in several tissues seems to be to facilitate or promote the mobilization of glucose and fatty acid reserves. In the liver, glucagon and the catecholamines cause an increase in the intracellular level of cyclic AMPby stimulating adenyl cyclase. This increase in the level of .cyclic AMP leads to a net increase in hepatic glucose production by at least three mechanisms: stimulation of phosphorylase activation, suppression of glycogen synthetase activity, and stimulation of gluconeogenesis. The catecholamines also stimulate adenyl cyclase in muscle and adipose tissue. Among the principal effects of cyclic AMP in these tissues are glycogenolysis in muscle and lipolysis in adipose tissue.
Definition
ChEBI: Cyclic AMP is a 3',5'-cyclic purine nucleotide having having adenine as the nucleobase. It has a role as a human metabolite, an Escherichia coli metabolite and a mouse metabolite. It is an adenyl ribonucleotide and a 3',5'-cyclic purine nucleotide. It is a conjugate acid of a 3',5'-cyclic AMP(1-).
Allgemeine Beschreibung
Cyclic AMP is a second messenger molecule comprised of an adenine ribonucleotide bearing a phosphate group bound to the oxygen molecules at the 3' and 5' positions of the sugar moiety. Cyclic AMP, which is synthesized from ATP by the intracellular enzyme adenylate cyclase, modulates the activity of several hormone-dependent signal transduction pathways.
Sicherheitsprofil
Human mutation data reported.When heated to decomposition it emits toxic fumes ofPOx and NOx.
Synthese
Cyclic AMP is synthesized from ATP by adenylate cyclase located on the inner side of the plasma membrane and anchored at various locations in the interior of the cell.[1] Adenylate cyclase is activated by a range of signaling molecules through the activation of adenylate cyclase stimulatory G (Gs)-protein-coupled receptors. Adenylate cyclase is inhibited by agonists of adenylate cyclase inhibitory G (Gi)-protein-coupled receptors. Liver adenylate cyclase responds more strongly to glucagon, and muscle adenylate cyclase responds more strongly to adrenaline.
cAMP decomposition into AMP is catalyzed by the enzyme phosphodiesterase.
